APPARATUS FOR DISTILLATION.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed July 24, 1905. SerialNn. 271,008.

citizen of the United States, residing at Louis-v ville, in the county of Jefierson and State of Kentucky, have invented certain new and useful Improvements in Apparatus for Distillation, of which the following is a specification.

My invention has for its object to simplify the apparatus required for the distillation of Whisky and other liquids and to make the process of distillation more closely continuous and rapid, roducing a larger yield and a f of the finished product in proto the amount of material used, also portion fully utilize and economize the heat required in the process.

The invention consists in the parts and combinations thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood, I have shown in the accompany: ing drawings means for carrying the'same into practical effect without limiting my improvements in their useful applications to the particular construction which for the sake of illustration I have delineated.

In said drawings, Figure 1 is a vertical sectional view of a distilling apparatus embodying my improvements, the illustration being to some extent diagrammatic. Fig.2 is a horizontal section on line II of Fig. 1. Fig. 3 is a sectional view on line III of Fig. 1. Figs. 2 and.3 are on a somewhat larger scale than Fig. 1.

Referring heater which may be to the drawings, B indicates a of any preferred con struction. As illustrated, it is formed with a somewhat elongated cylindrical casing into the lower end of which the beer or liquid to be distilled is forced or pumped through the pipe A. The heater is provided with longitudinal pipes C, through which such liquid passes to the upper end of the heater, where it passes out through the pipe D. The main chamber 1) of the heater surrounding the pipe C is heated by vapor from the still, which enters by pipe I at the top of the heater. The chamber b is inclosed at its ends by diaphragms 1 and 2, through which the pipes C open.

S indicates the still proper, which is divided into successive chambers 3, 4, 5, 6, and 7 by perforated diaphragms 8. The chamber 4 is connected with the chamber 5 for the downward passage of li uid by discharge-pipe G, which delivers the llquid into a hemispherical or other receiving and overflow cup H, the said pipe delivering, preferably, by a lateral opening formed by cutting off the lower end of the pipe at an angle, as indicated in Fig. 1. A similar connection is made from the chamber 5 to the chamber 6, from the chamber 6 to the chamber 7, and so on, according to the number of successive chambers which the still contains. A known means for delivering steam or other heating fluid to the lower end of the still S will be employed, the illustration of such means not being necessary to an understanding of my invention.

The said pipe D, passing downward from the top of the heater, enters the chamber 4 and delivers into a receiving-cup H, the pipe D, having, preferably, a lateral opening and the cup an upwardly and outwardly inclined bottom, as shown. From the chamber 4 the beer or liquid to be distilled works itself downward from chamber to chamber, as. is usual in stills of this character, the resulting distillate rising through the still, through the chamber 3, and into the vapor-pipe T. The pipe I is connected with the upper portion of .the heater-chamber b, in which chamber the vapor of distillation heats the li uid rising through the pipes C and is more or ess cooled thereby. In some stills heretofore known this partially-cooled vapor passes from the chamber 12 into a condenser; but by my improvements I have eliminated this condenser with advantageous results.

K is a discharge-pipe leading from the chamber 6, preferably in the directions and shape illustrated and delivering the vapor into the chamber M, which I term a doubler. The chamberM is superposed upon the topmost chamber of the still S, so as to be in immediate contact therewith, but is separated therefrom by a tight or solid partition m. The chamber M also surrounds a portion of the vapor-pipe I.

By the heat which is imparted from the pipe I to the chamber M the vapor in the latter is redistilled and a material amount of heat for this purpose is imparted from the still S by conduction through the partition m.

I may also employ in the chamber M addiment, for instance, as shown in Fig. 3, which proof of the finished coming back to t Such condensation of the watery and satu rated vapor as takes place in the lower part of the doubler is returned by the pipe 10 for redistillation, as described. Any spirits that have been condensed by contact with the watery or low-proof vapors are again liberated by the heat in the'doubler M.

r From the chamber M the vapor of distillation passes by ipe O to a condenser of known character for nal condensation into the finished product.

It will be observed that by my improve ments I attain several material advantages. The necessity for a first condenser between the still and the doubler is done away with, the process of distillation is continuous, and the second distillation does not require as much additional heat as in the ordinary still and process of distillation, thereby saving a large proportion of the fuel ordinarily required. A material amount of heat is saved because the vapor is not fully condensed and reduced in tem erature as much between the first and secon distillation as in the ordinary process and also because the largest part of the heat or in most cases all of it for the second distillation is procured from the still itself in which the first distillation takes place and from the vapor-pipe passing through the doubler and carrying the heated va or from the first distillation, by which sufficient heat is ordinarily sup )lied to redistill' the vapor lie doubler from the heater,

and, finally, by not condensing the vapor between the first distillation and the second distillation I produce a larger yield and a higher roduct in proportion to the amount of material used;

Any li uid of condensation in the heaterchamber b is returned by pipe 9* to the stillchamber 3 for distillation.-

ing from the doubler to the A. pipe 10, leadpipe 9 serves to draw oil from the doubler any li uid con densed therein for distillation in t e cham-' her 3.

I do not in this application claim the construction and'arrangement of the receiving cups H, diaphragms 8, and pipes which deliver to said cups, the same being claimed in my application, Serial N 0. 271,007, 24,1905. 1

What I claim is- 1. In a distilling apparatus the combina tion of a still, a doubler in immediate contact therewith, a heater for the incoming beer or liquid to he treated, said heater having a vapor-chamber in which the product of the still is divided into a liquid and a vapor and having also a separate space for the incoming beer,

v means for conducting the heated beer from the said heater to the still for distillation, a

vapor-conduit leading from the still through the doubler to the va or-chamber of the heater, a pipe for liquid leading from the lower part of the vapor-chamber of the heater to the still, and a vaporipe leading from the vapor-chamber of t e heater to the doubler, substantially as set forth.

2. In a distilling apparatus, the combination of a still, a doubler in immediate contact therewith, a heater for the incoming beer, said heater having a va or-chamber in which the product of the still is divided into a liquidand a vapor, and havingalso a separate space for the incoming beer, means for conducting the heated beer from the said heater to the still for distillation, a vapor-conduit leading from the still through thedoubler to the vaporchamber of the heater, afpilpe for liquid leading from the lower part c t e vapor-chamber of the heater to the still, the ipe K leading from the vapor-chamber of tlie heater near the lower part of the latter and thencepassing upward and then downward and communicating with the lower'part oithe doubler,

and means for conducting the vapor of high' proof from the doubler for condensation into finished spirit, substantially as setforth.

In testimony whereof I affix my signature in presence of two Witnesses.
